One day when the berries were about gone, Thorn saw a great herd of
reindeer going by.

"Oh, look at all the reindeer, grandfather!" he cried. "Where are they
going?"

"When summer comes," said Flint, "they go to a colder country; and when
summer ends, they come back to the cave country."

There were many reindeer in the herd, and their antlers looked like a
forest of trees without leaves. A big bear with hungry eyes was
following the herd.

That evening a young hunter made a picture of a beautiful reindeer with
his head among the grasses. Another hunter made a picture of two deer
that he had killed, and two live deer. Still another man made a handle
for a knife. He carved it from bone. It was like a deer springing.
The antlers were laid back on the neck, and the front legs were turned
under the body; the hind legs lay along the handle.

"Good!" said the other men as they looked at it.
